GRAIN-CARRIER FOR HARVESTERS.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed October 12, 1914. Serial N0. 866,325.

following is a specification.

This invention relates to improvements in gram carriers for harvesters and its ob]ect is to produce a device of this class that is at all times straw and grain tight and it come prises a plurality of metallic sections that overlap each other and each of which is securely fastened to a link of the chain of the upper and lower elevators of a self-binding grain harvester, or on the self-feeder of a thrashing machine, thus forming an endless apron.

With the foregoing and other objects in view the invention consists in the combina: tion and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claims and illustrated in the accompanying drawings which form; a part of said speci cation and in which Figure 1 is a vertical section through my improved grain carrier showing its attach ment to the elevator chain of a self-binding grain harvester. Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Like reference characters indicate corresponding parts throughout the several views.

The reference numeral 1 denotes one of the sprockets that carry the chain composed of links 2 that form the part of an elevator of a self-binding grain harvester. Every other link in the chain carries an angular support 3 to which a'flat bar 4 is secured that is formed at one end with an aperture 5 through which a pin 6 passes that is.

formed integral with a semi-cylindrical member 7, one of the edges of which bears upon the bar 4 through which its pin 6 passes and the other edge of which bears upon the non-apertured end of the adjacent carried by a nut'lO threaded upon the end of the said pin.

The members 7 together with the bars 4 form an endless apron that is flexible and straw and grain proof and that will adjust itself to suit the plane of travel of the chain formed of links 2. As the adjacent ends of bars 4 may rise and fall as they traverse a curvethe members 7 will also rise and fall and with them the pins 6 which are yieldin'gly retained in normal position by the springs 9 and the weight of the members 7.

What is claimed is:

1. A grain carrier for harvesters comprising in combination, a plurality of terminally apertured bars carried by alternate links in the elevator chain, pins extending through the apertured portions of said bars, semi-cylindrical members made integral with said pins and bearing upon the adjacent ends of successive bars and flexible supports for the apertured ends of said bars disposed about said pins.

2. A grain carrier for harvesters comprising in combination, a plurality of terminally apertured bars carried by alternate links in the elevator chain, pins extending through the apertured portions'of said bars, semi-cylindrical members made integral with said pins and bearing upon the adjacent ends of successive bars, apertured heads movable over said pins beneath said bars, nuts terminally carried by said pins and springs disposed between said nuts and heads.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two subscribing witnesses.
